Let's divide 99643644 by 690
Let's see how many times 690 fits into 99643644.

Let's proceed to step 1:
690 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 690

Advancing to step 2:
If we divide 99 by 690, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Grab the next digit (6) from the dividend, add it to 99, then carry on: 996 / 690

Let's proceed to step 3:
When dividing 996 by 690, we get 1 with a remainder of 306.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 306 after subtracting 690 from 996.
Grab the next digit (4) from the dividend, add it to 306, then carry on: 3064 / 690

Going ahead to step 4:
690 goes into 3064 4 times with a remainder of 304.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2760 from 3064 and we're left with 304.
Fetch the next digit (3) from the dividend, attach it to 304 and continue: 3043 / 690

Step 5:
690 goes into 3043 4 times with a remainder of 283.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Deduct 2760 from 3043 and we're left with 283.
Append the next digit (6) from the dividend to 283 and continue with: 2836 / 690

On to step 6:
690 goes into 2836 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1444.0
If we subtract 2760 from 2836, we get 76.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 690

Step 7:
The number 690 fits into 764 1 times, leaving a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 14441.0
Subtracting 690 from 764 leaves us with 74.
Grab the next digit (4) from the dividend, add it to 74, then carry on: 744 / 690

On to step 8:
When dividing 744 by 690, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 144411.0
Subtract 690 from 744 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
When dividing 540 by 690, we get 0 with a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 144411.0
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 10:
690 can be fit into 5400 7 times, resulting in a remainder of 570.
Put 7 as the next digit of the answer. 
Result so far: 144411.07
Subtract 4830 from 5400 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 11:
690 can be fit into 5700 8 times, resulting in a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 144411.078
Subtract 5520 from 5700 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
690 can be fit into 1800 2 times, resulting in a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 144411.0782
If we take 1380 away from 1800, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 13:
The number 690 fits into 4200 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 144411.07826
The remainder is 60 after subtracting 4140 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
600 divided by 690 is 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 144411.07826
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 15:
When dividing 6000 by 690, we get 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 144411.0782608
Subtract 5520 from 6000 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
690 can be fit into 4800 6 times, resulting in a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 144411.07826086
Subtract 4140 from 4800 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The final outcome is 144411.07826086, with a leftover of 6.6e-07.
